ROOF-FLASHING.

Specification of Letters Patent.

Patented Jan. 222, 1 .91%.

Application filed January 17, 1917. Serial No. 142,838.

To all whom it may concern:

Be it known thatI, GEORGE E. Swanson, a citizen of the United States, residing in Wayne Junction, county of Philadelphia, and State of Pennsylvania, have invented new and useful Improvements in Roof- Flashings, of which the following is a specification. Y

My invention comprises an improved flashing adapted specifically for the joint or corner between a building roof and an adj acent building wall, and consists essentially in an improved form of raggle block, or groove in the vertical wall, adapted to receive the flashing- The flashing may be of the same material that is used for covering the roof, or sheet metal, roofing slate, or

ready roofing.

My invention further consists in placing a cant strip in the corner formed by the roof and the vertical wall, with its face at an angle preferably of about with the roof, and in forming in a raggle block or in the solid wall, an upwardly inclined groove in alinement with the face of said strip, said groove being of sufficient width to freely receive, and afford opportunity for move ment of the flashing, due to expansion and contraction of the roof covering or structure, the upper edge of said cant strip being in substantially the same plane as the lower wall of the groove.

My invention further consists in the features of construction hereinafter described, claimed, and shown in the accompanying drawings forming part hereof.

In the drawings, Figure 1 is a perspective sectional view of a wooden roof deck and adjacent brick wall, the roof covering extending over the cant strip and abutting against the wall, the flashing overlapping the roofing on the cant strip and extending into the raggle groove.

Fig. 2 is a modified construction showing an integral concrete roof deck and wall, the raggle groove being molded in the wall, and the roofing and flashing applied as in Fig. 1.

Fig. 3 shows a wooden roof deck, and an adjacent wall covered with a sheet metal roof, the projecting edge of the roofing itself entering the raggle groove and constituting its own flashing.

face of the building wall a short distance above the roof deck, as shown also in Fig. 3, is a raggle block 3, preferably of the dimensions of two bricks, having an upwardly inclined groove 4:, formed in the block.

In the angle formed by the roofing deck and wall is set a cant strip 5, the face of which with the roofing 2 thereon, is in alinement with the bottom of the groove 4. Inserted in-this groove and extending down to the roof level over the cant strip is the flashing 6, which may consist of ready roofing, sheet metal, roofing slate, roofing tile, or any suitable material.

Where a concrete construction is employed, as shown in Fig. 2, the corner may wall 8. The roofing 2 extends across the face of the filled-in corner to the raggle groove 7, and the flashing 6 is inserted into the raggle groove 7 and extends down to the roof level.

In Fig. 3 the roof covering isof sheet metal, the roofing itself being carried into the raggle groove and serving as its own flashing.

One of the merits of my invention is the factthat the flashing is not fastened in the raggle groove thus permitting its free movement in the groove with the expansion and contraction of the roof covering or structure to which it is connected or of which it is a part and avoiding thecracking and formation of leaks therethrough.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In combination with a building roof and an abutting vertical wall, a flashing lying in a plane at an obtuse angle with said roof and extending therefrom into a groove in said wall, and being free to move therein as affected by expansion and contraction due to varying weather conditions.

2. In combination, a building roof, an abutting wall having an upwardly inclined groove, and a cant-strip in theincluded an gle the face of which alines with the lower wall of said groove and an extension of the roof covering overlying the cant-strip and extending loosely into said groove.

3. In combination with a building roof, an abutting wall and a cant-strip in the intili ' eluded angle, an element in said wall having 4. In'combination with a building roof, an

abutting wall and a cant-strip in the included angle, an element in said wall having an upwardly inclined groove, the lower wall of the groove being in substantial alinement with the face of said cant-strip, adapting the groove to receive flashing material to connect a roof covering with the wall without any part of said flashing material being arranged in a vertical position.

5. In combination with a building roof,.an adjacent upright wall and a triangular cantstrip fitted to the intermediate angle, said wall having an upwardly inclined groove,

the lower wall of which is in substantial alinement with the face of said cant-strip, a flashing strip overlying said cant-strl and extending wholly in a nonverticalposition into said groove and being free to move therein as affected by the expansion and contraction of the roof covering.

6. In, combination, a building roof, an

' abutting vertical, grooved wall, a triangular block, a triangular cant-strip fitted to the angle between the roof and wall with its face in alinement with the lower wall of said groove, and a' flashing strip overlying said cant-strip and projecting into said groove being free to move therein as affected by the expansion and contraction of the roof covering or the building structure. v

Signed "at New York, in the count of New York, and State of New York, this 13 day of Jany.. 1917.
